Steve,

I am sure you can guide me to solve this mysterious problem. I have been trying to solve this problem for two months! including local MB dealer.

Car only runs after cranking few times without any hesif I pour few ounces of fuel in air intake. But, once switched off, can't restart. I have replaced the following:

1. plugs, fuel accumulator, fuel pump, dist. cap & rotor
2. Dealer said the disch. pressure & flow is okay. They told me to replace cap & rotor, but no help.

What else should be checked?
